In-depth analysis of tipper accidents and solutions
A dump truck is a special-purpose vehicle that uses its own engine power to drive a hydraulic lifting mechanism, unloading its car at a certain angle, and resetting it by its own weight. At present, the engineering dump trucks are used in a large amount, resulting in huge economic benefits, and the subsequent safety problems are becoming increasingly prominent. “Rollover†is the main safety issue for engineering dump trucks, causing a large number of casualties and property losses every year. There is currently no product on the market that can effectively prevent dumping accidents of engineering dump trucks. The engineering dump truck can only rely on the driver's own feeling to judge the balance of the vehicle in the process of parking leveling and bucket lifting.
Dump truck dumping is mainly caused by the following points. 1. Unloading the ground is not smooth, if the ground is not smooth enough will cause the truck to heartily offset, the ground in the dump site must be flat, especially left and right can not be biased. 2. The ground is not strong enough, because when the unloading vehicle, the rear wheels will be soft on the land, it is easy to cause sagging, and also easily cause overturning 3. The driver forgets to forget to open the rear tailgate before unloading, so with the hydraulic cylinder Increasingly, the center of gravity of the entire vehicle is constantly rising. If the center of gravity shifts slightly, the consequences will be disastrous!
This article will propose a feasibility plan based on the reasons for the occurrence of rollover: First, on the flatness of the unloaded ground, we can determine the level of inclination sensors installed in the car, and we can test the safety of a loaded cargo in an experimental test. The tilt range of the ground, this range includes the left and right angle range and the front and rear angle range. If it is out of range, it will prompt the driver’s current angle and prompt the driver that the vehicle is not currently unloadable. If the ground is not strong enough, we can change the angle of the vehicle when the cargo is unloaded. If the change is too large, it means that the position of the center of gravity of the vehicle is changing and the surface of the surface is not strong enough. At the same time, the cab prompts the driver through the alarm device. The switch problem of the tailgate can use the proximity switch to output the corresponding electrical signal to determine the current switch state. At the same time, another tilt sensor can be installed on the work plane of the unloading box to monitor the current tilt angle in real time. Tianjin Huaxing Chengda Electronic Technology Co., Ltd. is a professional manufacturer of industrial tilt sensors and also provides corresponding system designs. This program has a strong implementation.
The consequences of tipping over the dump truck are not only causing serious damage to the vehicle, but also to a certain extent the life safety of the dangerous dangerous driver. The system scheme put forward by Huaxing Electronic has avoided the problem of side dumping of the dump truck. . Not only ensure the safety of the vehicle, but also provide a good safety guarantee for the vehicle driver. The system uses a CAN bus to connect the vehicle’s tilt sensor, proximity switch and smart display instrument in the cab. The system is easy to install, has good anti-interference, and has good practical value and market prospects. Reprint please specify: http://?410.html
